clReleaseKernel

Decrements the kernel reference count.

cl_int clReleaseKernel(cl_kernel kernel)

Notes

The kernel object is deleted once the number of instances that are retained to kernel become zero and the kernel object is no longer needed by any enqueued commands that use kernel. Using this function to release a reference that was not obtained by creating the object or by calling clRetainKernel causes undefined behavior.

Errors

Returns CL_SUCCESS if the kernel objects are successfully alloctaed. Otherwise, it returns one of the following errors:

• CL_INVALID_KERNEL if kernel is not a valid kernel object.

• CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.

• CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.
